New one on me

Ive had my Lyman 2000 electronic scale turned on on my bench for two days. I was planning on loading some ammo just to pass the time. I sat down, calibrated it, everything went well. I checked it with my check weights everything as it should be. I placed my empty pan on the scale and noticed it was heavier than usual, I cleaned it thoroughly and tried again, once again it's heavier. I got the check weights out, they weight perfect. It seems for some reason the plastic powder pan is causing wired weights. If I put it on and take it off it seems to get heavier, I rezero often but it won't settle down. Check weights confirm scale is right on, my RCBS 10 10 confirms check weight are on. Any ideas why the plastic powder pan is causing strange readings?
Static?
 
Cold weather could be causing more static. Also, is your lighting fluorescent or regular incandescent light bulbs? Fluorescent bulbs have caused accuracy problems with electronic scales.
Also, keep your phone in the other room, anything Bluetooth or cellular, fluorescent lighting, etc. all will affect an electronic scale!
 
My wife has a smart watch and when she enters into the reloading room the electronic scale won't calibrate,could not figure that out until your post 33dude

This is what I use
